Lo de psicología del proceso de trabajo me rechina. La psychology-of-working pretende ser un perspectiva integradora que aúna distintos análisis en torno al trabajo y al desarrollo profesional. Dado que no existen traducciones formales al castellano del trabajo de L. Blustein, utilizaría la idea de psicología del trabajar, en tanto que concepto amplio de sentido y diferenciado de la psicología del trabajo u ocupacional, manteniendo en cualquier caso la denominación original entre paréntesis y en cursiva en primera instancia -psicología del trabajar (psychology of working)- por mor de aclaración.


In this chapter (and in many chapters within this Handbook), the term “psychology of working” is used to capture both the critique of the extant foci and emphases in the work-based psychological disciplines as well as the emerging perspective that seeks to encompass the full range of working experiences for the full range of individuals who work and who want to work.

The psychology-of-working perspective reflects decades of sustained critique of the traditional array of assumptions and perspectives about work and career.
